Can you renovate a bathroom as part of a larger project?

Yes — a significant number of our bathroom renovations are delivered within wider house extensions, loft conversions, or whole-house refurbishments. Coordinating the bathroom fit-out within the overall construction programme is something we manage as a matter of course, ensuring that first-fix and second-fix stages happen at the right point in the build.

Do you install wet rooms?

Yes. We design and install fully tanked wet rooms with gradient floors, linear drainage systems, and frameless glass screens. Wet room installation requires precise waterproofing and careful floor preparation — particularly on timber-framed floors common in South London's older properties. We use proven tanking systems and test everything before tiling begins.

Can I stay in my home during a bathroom renovation?

In most cases, yes. We manage dust, noise, and access carefully. If only one bathroom is being renovated and there is no alternative, we plan the work to minimise the time you are without a working bathroom — typically no more than a few days during the plumbing changeover phase. For larger projects involving multiple bathrooms, we discuss the logistics openly at the planning stage.

Do you supply the sanitaryware and tiles, or do I source them myself?

We can work either way — supply and fit, or fit only. Some clients prefer to choose and order their own fixtures and tiles, in which case we advise on what to order and when so materials arrive at the right point in the programme. Others prefer us to supply everything against an agreed specification. Either approach works, and we are happy to guide you through the selection if that is helpful.

Do you handle the plumbing and electrics yourselves?

Our plumbing work is carried out by experienced, qualified plumbers who work with us consistently on every project. All electrical work is completed by qualified electricians in full accordance with Part P of the Building Regulations. Every plumbing and electrical installation is tested and certified at handover.

What guarantee do you offer on bathroom renovation work?

Every bathroom project is covered by Integral Builders' structured workmanship guarantee, alongside manufacturer warranties on individual products and fixtures. Full public liability insurance and contract works insurance are in place on every project. All documentation is issued formally at handover.

A Considered Approach

Bespoke Bathroom Renovations Tailored to Your Home

A bathroom renovation might seem smaller in scale than a house extension or a full home renovation, but the complexity per square metre is often greater. Plumbing, drainage, waterproofing, ventilation, electrical safety regulations, tiling, underfloor heating, heated towel rails, bespoke storage — everything has to come together in a room where there is very little margin for error. A poorly waterproofed shower tray or a drainage fall that is a degree off will cause problems that show up months later, long after the tiler has left.

That is why we approach every bathroom refurbishment in South London with the same structured project management we bring to our larger residential schemes. Whether it is a small bathroom renovation in a ground-floor cloakroom of a Victorian terrace, a complete family bathroom refit in a 1930s semi, or a new en-suite bathroom installation as part of a loft conversion, we plan the work properly, coordinate every trade in the right sequence, and finish to a standard that holds up to daily use for years.

As experienced bathroom renovation specialists, we work across South London — from Wimbledon and Wandsworth to Putney, Tooting, Balham, Clapham, Merton, and into Surrey — with a particular understanding of the period properties, compact layouts, and older pipework that characterise this area's housing stock.

Designed Around How You Actually Use the Space
Every bathroom brief starts with the practical realities who uses the room, at what times of day, what storage is actually needed, and whether a bath, a walk-in shower installation, or both makes more sense for your household. Not a catalogue of fixtures, but a room that works..
Architect & Designer Collaboration
When a bathroom forms part of a wider house refurbishment or an architect-led project, we work alongside the design team to deliver the specified layout, finishes, and materials faithfully — from tile patterns to brassware selections.
Proper Trade Coordination
Bathroom plumbing first, then electrics, then tanking and waterproofing, then bathroom tiling. Getting the sequence wrong causes problems that surface months later. We programme every bathroom project with the same discipline we apply to structural building work.
Quality That Lasts
Waterproofing done correctly. Tiles cut and laid with care. Grouting finished cleanly. Fixtures installed to the manufacturer's specifications. Professional bathroom installation means you are not calling someone back six months later.

Our Capability

Bathroom Renovation Services in South London

From compact cloakrooms to complete bathroom remodels within larger renovation projects, our capability covers every type of residential bathroom work across South London.

Family Bathroom Renovations

A complete bathroom refit of the main family bathroom — strip-out of existing fittings, new plumbing and drainage, waterproofing, tiling, sanitaryware, storage, bathroom lighting installation, and ventilation.

En-Suite Bathroom Installation

Bespoke en-suite bathroom installations delivered as part of bedroom refurbishments, loft conversions, and period property renovations. We carefully manage plumbing routes, drainage falls, and ventilation, particularly in converted roof spaces and older Edwardian and Victorian properties where floor depths and joist directions can create technical challenges.

Wet Room Design & Installation

Fully tanked wet rooms with gradient floors, linear drainage, and frameless glass screens offer a practical, clean alternative to traditional showers. Ideal for smaller bathrooms, shower room renovations, and accessible ground-floor conversions where ease of use and accessibility matter, we also provide bath-to-shower conversions with walk-in designs.

Cloakroom & Guest WC Renovations

Thoughtful cloakroom and guest WC renovations make the most of compact, awkward spaces in South London’s Victorian terraces and period homes. We use considered layouts, wall-hung sanitaryware, and smart storage to maximise every centimetre.

Luxury Bathroom Refurbishments

High-specification luxury bathroom renovations featuring natural stone finishes, bespoke vanity units, freestanding baths, digital shower systems, underfloor heating, bathroom lighting design, and architect-specified materials throughout. The same attention to bespoke bathroom design and detail that defines our home renovation projects across South London.

Bathrooms Within Larger Renovation Projects

Many bathroom renovations form part of wider extensions or whole-house refurbishments. We carefully coordinate first-fix plumbing, tiling, and sanitaryware with the wider construction programme, ensuring each stage is completed in the right order and finishes are protected through to handover.

Architect Collaboration

Working Alongside Architects & Designers

When a bathroom is part of an architect-led project, the specification often includes particular tile layouts, brassware finishes, lighting positions, bathroom ventilation requirements, and bespoke joinery that cannot be improvised on site. Our role is to read the drawings carefully, raise anything that needs clarifying before we start, and then deliver exactly what has been designed.

We work comfortably from detailed architectural drawings, interior design specifications, and material schedules — translating them into a finished bathroom that matches the designer's intent. For bathroom renovation projects that sit within a larger scheme, we coordinate the bathroom fit-out within the overall construction programme so that trades do not clash and finishes are protected through to handover.

Case Study

A complete family bathroom and en-suite renovation within a Victorian terrace refurbishment

A full renovation of the family bathroom and a new en-suite bathroom installation on the first floor of a Victorian terrace in South London, delivered as part of a wider home renovation project. The brief was to replace dated fittings with a clean, contemporary bathroom design while respecting the proportions and character of the original house.

The family bathroom involved re-routing existing pipework from the original layout, installing underfloor heating on a suspended timber floor, and laying large-format porcelain tiles with minimal grout lines. The en-suite required careful coordination of drainage falls within the existing floor depth, and a fully tanked wet room area with a frameless glass screen and a bespoke vanity unit designed to fit the available wall space.

Scope:

Family bathroom + en-suite renovation

Context:

Part of a wider whole-house refurbishment

Duration:

6 weeks (bathroom phase)

Finish:

Large-format tiles, bespoke vanity, underfloor heating, wet room tanking

Bathroom-Specific Expertise

We understand the technical demands that set bathroom fitting apart from general building work — waterproofing systems, drainage gradients, ventilation regulations, electrical zones, and underfloor heating on timber floors. This is not a sideline for us. It is a core part of what we deliver as bathroom fitters in South London.

Experienced Project Coordination

Every bathroom renovation is run by a dedicated project manager who coordinates plumbing, electrical, tiling, and joinery trades in the right order. No improvising, no trades clashing, no rework.

Collaborative Approach with Designers

When your bathroom has been designed by an architect or interior designer, we deliver what they have specified reading the drawings properly, pricing transparently, and raising questions before we start rather than making assumptions on site.

Attention to Detail

Tile cuts at edges. Silicone lines. Grout consistency. Fixture alignment. Drainage testing. The small things that separate a bathroom that looks good on handover day from one that still looks good two years later.

Quality Workmanship

A directly employed core team supported by vetted specialist trades — the same qualified plumbers, tilers, and electricians on every project. No rotating subcontractors. Consistent standards backed by a structured workmanship guarantee.

Reliable Communication

You will know what is happening and when. Progress updates at each stage of the fit-out, honest timelines, and a single point of contact throughout. If something changes, we tell you straight away — the way a trusted bathroom renovation company should operate.

Structured Delivery Process

From the initial survey through to snagging and certification, every bathroom project follows the same structured process. Properly planned, properly documented, properly finished.

Frequently Asked Questions

Bathroom Renovations

A straightforward bathroom renovation — strip-out, re-plumb, re-tile, and new sanitaryware — typically takes 3 to 5 weeks on site. More complex projects involving structural changes, underfloor heating, bespoke joinery, or wet room tanking may take 5 to 8 weeks. When the bathroom is part of a larger home renovation, the bathroom phase is programmed within the overall build schedule. We issue a clear timeline before work begins.

Costs depend on the size of the room, the specification of fixtures and finishes, and the extent of plumbing and structural work involved. As a general guide, a mid-range family bathroom renovation in South London typically falls between £12,000 and £25,000, while a high-specification luxury bathroom refurbishment with bespoke joinery, natural stone, and underfloor heating can range from £25,000 to £45,000 or more. We provide a fully itemised bathroom renovation quote so you can see exactly where every pound is going — no hidden costs, no vague allowances.

We cover all of South London and Surrey, including Wimbledon, Wandsworth, Putney, Tooting, Balham, Clapham, Merton, Raynes Park, Streatham, Croydon, Kingston, Sutton, and surrounding areas. Our team is based in Wimbledon Chase (SW20), putting us right at the centre of the area we serve. Whether you need bathroom renovations in Wimbledon or bathroom fitters in Wandsworth, we are local and available.

Most bathroom renovations do not require planning permission, but Building Regulations apply to electrical work (Part P), drainage changes, and structural alterations. If you are creating a new bathroom in a space that was not previously a wet room — such as within a loft conversion — there are additional drainage and ventilation requirements. We manage the Building Regulations process as part of the project so you do not need to coordinate it separately.
